The viscaction scheme of Viskos-Inviscid in a house code called "Foil" is evaluated using Airfoil LS (1) 04-17 for an attacking angle to 20 to 20 degrees. Calculations are carried out for cases of Reynolds numbers of 5.7x106 based on the availability of experimental data. Excellent results are obtained for an angle of attack -5 to 13 degrees. For the attacking angle of 14 to 20 degrees, the increase in the prediction of the separation point is taking place. The results of the inhouse code are compared with the experimental data and the results of the freeware software called �Javafoil� and �xfoil�. Experimental data was taken from the NASA report specifically discussed Airfoil LS (1) 04-17. Keywords: viscous-inviscid interaction, airfoil
